Floating structure of coaxial connector
Provided is a floating structure of a coaxial connector having a floating function and ensuring a reliable connection and water cutoff property are ensured. The floating structure of the coaxial connector includes: a plug introduction hole having an inner diameter larger than an outer diameter of the plug; an enlarged diameter hole communicating with the tip side of the plug introduction hole; a locking ring fixed in the enlarged diameter hole; a slider having a slide ring disposed movably in the axial direction and the axial radial direction; and an energizing elastic member that energizes the slide ring toward the locking ring. The plug body is coupled to the slider, and the plug body is held in the plug insertion part movably in the axial direction and the axial radial direction.
1. A floating structure of a coaxial connector comprising:
a plug having a plug body connected with a flexible coaxial cable; and
a receptacle housed in a case,
the plug, inserted into a cylindrical plug insertion part formed in the case, and the receptacle being coupled to each other,
wherein
the plug insertion part is formed with a plug introduction hole having an inner diameter larger than an outer diameter of the plug, and
an enlarged diameter hole communicating with a tip side of the plug introduction hole and having a diameter larger than a diameter of the plug introduction hole,
the plug insertion part includes
a locking ring fixed in the enlarged diameter hole,
a slider having a slide ring disposed movably in an axial direction and an axial radial direction between a bottom of the enlarged diameter hole and the locking ring, and
an energizing elastic member that energizes the slide ring toward the locking ring,
the plug body is coupled to the slider, and
the plug body is held in the plug insertion part movably in the axial direction and the axial radial direction,
wherein
the slider includes a holder part into which the plug body is inserted, and
an engagement spring body that engages with an engagement protrusion projected from an outer periphery of the plug body is provided on a tip side of the holder part.
2. The floating structure of the coaxial connector according to claim 1 , wherein
the plug includes a cap made of an elastic body that fits outside the coaxial cable and fits into an introduction-side opening of the plug insertion part, and
the cap seals the plug insertion part, and the plug body is held on the cap via the coaxial cable.
3. The floating structure of the coaxial connector according to claim 2 , further comprising
a cover body having a top plate part projected outward from the cap and a cylindrical outer peripheral part supported by the top plate part,
the outer peripheral part is formed with an engagement hole that engages with an engagement projection projected from an outer periphery of the plug insertion part.
